The “Mobile” Menu button (which condenses all menu options on mobile devices) does not work (it does not expand) on the blogs HOME page, that is, the URL specified when the header image is clicked. If I navigate directly to a different page (i.e. About) using its URL, then the mobile menu button works fine to go to the other pages. But anytime I go back to the “Home” URL, the menu button is no longer clickable.
In effort to troubleshoot I deactivated all plugins and still had the issue.
